A/N: This is the third story in the series. The first two are called "Harmony," and "The Harvesting Darkness." If you haven't read those, well, this is a crossover so I think I'm OK to do this...

So here's what's been happening on Doctor Who. The Doctor showed up at McKinley and couldn't get back in the Time Vortex because an alien in the basement was trying to change the history of the whole universe. Yikes. The Doctor saved the day, but to fix the changes to the timeline he had to let the glee club re-live their timeline. And Quinn couldn't stay because now she's from a redundant timeline, so she's traveling with the Doctor until she finds a place to settle down. And that's what you missed on Doctor Who.

Afternoon of the Fourth Day

The Siborean talks had broken down, just like everyone had said they would. The members of the colony world Fragaria weren't expecting anything different, after all. They'd been down this road before and, ultimately, nothing ever changed. Of course it had all been going well until the Siborean ambassador was assassinated, but the general population didn't know about that. No political group would take responsibility for the assassination, not that it would have mattered at this point anyway. It was too late for the government to simply turn over the perpetrators. Now the Siborean war council had been called in, there was no turning back. Peace hadn't been the ultimate goal, but at least mutual coexistence had been hoped for. There was no chance for that now. Now there was just nothingness.

Daniel Parker stood alone, just outside the hangar door, watching the faraway city over the vast plains separating them. The worst thing, he though, was being alone. He knew what was coming; the vast array of equipment inside the lab gave him a uniquely clear picture of the happenings far above, in orbit of the planet. The government hadn't told the people anything. Maybe that was for the best. Because the knowing without being able to do anything about it was nothing short of horrific.

The end was coming, in a matter of moments, and as he stared out over the city he had just one regret; that his parents' research would never be completed. All he wanted out of life since they had died was a chance to carry out their work, and publish their findings under their names, as a tribute to those he cared about, and who had most cared about him. That would never happen now. As he looked out towards the city, a sparkling light streaked into view from the upper atmosphere. It flew down towards the spire at the very center of the spaceport, and when it landed, he was nearly blinded by a white flash. The last thing he knew was the sensation of a great heat washing over every single bit of his being.

The Doctor kicked at a blackened, charred piece of metal. "Such a waste," he muttered.

Quinn stood behind him, leaning against the door frame of the TARDIS, with her arms cradled protectively around her middle. "What happened?"

"Hard to say," he replied. "A war of some kind, most likely. Mutual annihilation, or maybe an unprovoked attack." The TARDIS had materialized on the ruins of a once great city. The remains of great spires and buildings could still be seen off in the distance. A large tower had once stood at the center of the city, with an array of smaller buildings around it. If they looked to the distance, they could see a large alcove carved into the cliff face, miles away.

"Do you have any idea who did this? Couldn't you, I don't know... analyze the weapon signature or something?"

He chuckled lightly. "Possibly, if this were anything more cunning than an explosion. It's not, though. And one nuclear explosion pretty much looks like any other."

"That's all this was? A nuke, like from my time?"

He shook his head. "Oh no. If there's one thing that never stops, Quinn, one thing that never, ever changes, it's this: people always get better and more clever at killing one another. Just a nuke? Sure, same basic principle applies; compress enough fissionable material and off you go. The question becomes, what fissionable material? How can you lose less energy in the conversion to increase the yield of the reaction? How can you chain the devices together for greater destruction? Yes, it's like your time, only much more deadly. And it's such a shame."

She took a few tentative steps out of the relative safety of the Police Box. "Who were they?"

He shrugged. "Nobody knows. Kept to themselves, really. There's not even a note in the TARDIS' databanks, and you know how rare that is. It was called Fragaria colony, according to the sign in the spaceport."

She nodded. "I wonder what they were like."

"History will never know."

They stood silent for a moment, her leaning against his arm now, holding his right hand in her left. They kept silent watch, then she said, "Why don't we go find out?"

He looked down at her. "How d'you mean?"

She sighed. "Somebody should remember them," she said. "Even if it's just us."

Now he sighed. "Hmm. Could you do it, though?"

"Do what?"

"Could you really look at them, get to know them... knowing what's coming? Because this," he said, nodding towards the rubble, "doesn't change. History says there's no civilized planet here and we're not going to argue the point. Not this time, not here."

She thought about it for a moment. "No references? Not in the TARDIS, not in a history book, nothing?"

"None, " he replied.

She looked out over the vast fields of destruction, taking in all the details. "When I was a little girl, my parents took me to the Vietnam War memorial. My dad was a soldier - did I ever tell you? There's a huge age gap between him and my mom. I was only nine. And that wall, it just stretched on forever, engraved with names, top to bottom.

"My dad was looking for a name, his squad leader, and he couldn't find it. I didn't really understand what it was about or why it mattered to him, but I told him I was sorry we couldn't find his friend. He said that it was alright and it didn't matter, because as long as there were people like us, coming to the memorial and remembering everyone that was lost, then those people would never really be gone." She looked at him. "It's not about our curiosity. It's a question of honor."

He smiled at her. "Who can argue with that? Allons-y!" And he bounded back inside the TARDIS.
